WCF 相关配置

WCF错误：413 Request Entity Too Large

在我们用WCF传输数据的时候，如果启用默认配置，传输的数据量过大，经常会出这个错误。

WCF包含服务端与客户端，所以这个错误可能出现在服务端返回数据给客户端，或客户端传数据给服务端时。

1. 服务端返回数据给客户端报错

在客户端配置文件中，主要是配置maxReceivedMessageSize

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="ServiceProxyBinding" closeTimeout="00:10:00" receiveTimeout="00:10:00" endTimeout="00:10:00" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
          <readerQuotas maxStringContentLength="134217728" />
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://localhost:5239/AHMTService/PartService.svc" binding="basicHttpBinding" bindingConfiguration="ServiceProxyBinding" contract="UniCloud.ServiceContracts.IPartService" name="IPartService" />
    </client>
  </system.serviceModel>

2 客户端传数据给服务端报错

 修改服务端web.config,主要也是配置maxReceivedMessageSize

<system.serviceModel>
    <services>
      <!--DecodeService 服务端配置 增加接收文件大小-->
      <service name="UniCloud.Services.DecodeService" behaviorConfiguration="MyServiceBehaviour" >
        <endpoint address="" binding="basicHttpBinding" bindingConfiguration="MyServiceBinding" contract="UniCloud.ServiceContracts.IDecodeService">
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:5239/AHMTService"/>
          </baseAddresses>
        </host>
      </service>
    </services>
    <bindings>
      <basicHttpBinding>
        <binding name="MyServiceBinding" closeTimeout="00:10:00" receiveTimeout="00:20:00" sendTimeout="00:20:00" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
          <security mode="None"></security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MyServiceBehaviour">
          <!-- 为避免泄漏元数据信息，请在部署前将以下值设置为 false -->
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <!-- 要接收故障异常详细信息以进行调试，请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息 -->
          <serviceDebug includeExceptionDetailInFaults="true" />
          <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <protocolMapping>
      <add binding="basicHttpsBinding" scheme="https" />
    </protocolMapping>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

其实要修改所有的服务，不管是服务端还是客户端，Binding那边增加一个没有设置名字的默认配置就OK了

 <binding closeTimeout="00:10:00" receiveTimeout="00:20:00" sendTimeout="00:20:00" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"></bindging>
